This reverts commit b65f813c1a.
As a side effect this also seems to fix wtap which seems to have
lost the epoch over the input path in between.

This brings it inline with what's in openbsd. I tested it locally
with 2G and 5G association; it seems to work.

Summary:
This updates the if_iwmreg.h definitions to;
OpenBSD: if_iwmreg.h,v 1.65 2021/10/11 09:03:22 stsp Exp
A few things haven't been fully converted, namely:
* I left a couple things as enums for now just to reduce the
other diffs needed; but they're the same values
* The IWM_SCD_QUEUE_* macros have different offsets which I
didn't update in case they broke things / changed based on later
firmware. But they also may be real bugfixes which are needed
for later chips. It'll need more testing before flipping this on.
The c file updates are:
* Use the newer names for things if the name changed but the semantics
didn't
* Explicitly use the earlier firmware structs which maintain compat
with the current firmware and code. The newer ones are in here and
they'll get converted when more openbsd code is merged into this tree.
* Use the older iwm rate table for now, which has entries for legacy
rates, HT and VHT. Our code works with that right now, updating it
to openbsd's err, "different" version can be done at a later date
when HT/VHT support is added.
Notably, a bunch of definitions were deleted that weren't used.
They're not used either in the openbsd/dfbsd drivers so I think it's
safe to delete them in the long run.

While IEEE80211_R_BAND was defined, there was no place to store the
band. Add a field for that, adjust ieee80211_lookup_channel_rxstatus()
to require it, and update drivers passing "R_{FREQ|IEEE}" in already to
provide the band as well. For the moment keep the fall-back code
requiring all three fields.

In r365419 ieee80211_media_change() callers were updated to not longer
act on the obselete ENETRESET return code.
While in the old days iwm has done a stop/init cycle in these cases,
this was not executed since r193340.
As a consequence simplify iwm code as well by passing ieee80211_media_change()
right to ieee80211_vap_attach() as there is no more need for a local
implementation.

X-MFC: fix is already in stable/12

In r178354 with the introduction of multi-bss ("vap") support factoring
out started and with r193340 ieee80211_media_change() no longer returned
ENETRESET but only 0 or error.
As ieee80211(9) tells the ieee80211_media_change() function should not
be called directly but is registered with ieee80211_vap_attach() instead.
Some drivers have not been fully converted. After fixing the return
checking some of these functions were simply wrappers between
ieee80211_vap_attach() and ieee80211_media_change(), so remove the extra
function, where possible as well.

Previously the driver handled the bit within itself, but did not expose
the state change to net80211 and interface layers.
This change uses net80211 KPI for rfkill signaling.
The code is modeled after similar code in iwn and wpi.

Make sure all occurrences of ieee80211_input_xxx() in sys/dev are
covered by a network epoch section. Do not depend on the interrupt
handler nor any taskqueues being in a network epoch section.
This patch should unbreak the PCI WLAN drivers after r357004.

This was inherited from iwlwifi, which drives devices supported by both
iwn(4) and iwm(4) in FreeBSD. In iwm(4) _mvm is meaningless, so remove
it. OpenBSD made the same change a long time ago. No functional change
intended.

This is the multiqueue receive code required for 9000-series chips.
Note that we still only configure a single RX queue for now. Multiqueue
support will require MSI-X configuration and a scheme for managing a
global pool of RX buffers.

For now iwm only ever uses queue 0 and the management queue, but my 9560
raises a software error interrupt during initialization if this flag is
not set. iwlwifi sets it for all 7000- and 8000-series hardware, so we
might as well do it unconditionally.

Match such chips using the device ID. We should really be checking the
subdevice as well, since a smaller number of 9460 and 9560 devices
actually belong to a new series of devices and require different
firmware, but that will require some extra logic in iwm_attach().
